84457980 ÷ 48 
We're looking to find how many times 48 goes into 84457980.

Let's proceed to step 1:
48 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 48

Advancing to step 2:
84 divided by 48 is 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 36 after subtracting 48 from 84.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 48

Let's proceed to step 3:
The number 48 fits into 364 7 times, leaving a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Deduct 336 from 364 and we're left with 28.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 48

Going ahead to step 4:
285 divided by 48 is 5 with a remainder of 45.
The next digit of our result is 5. 
Result so far: 175.0
Subtract 240 from 285 to get 45.
Grab the next digit (7) from the dividend, add it to 45, then carry on: 457 / 48

On to step 5:
If we divide 457 by 48, we get 9 and a remainder of 25.
Record the quotient 9 as the next digit in the result. 
Result so far: 1759.0
Subtract 432 from 457 to get 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 48

Let's proceed to step 6:
When dividing 259 by 48, we get 5 with a remainder of 19.
The next digit of our result is 5. 
Result so far: 17595.0
The remainder is 19 after subtracting 240 from 259.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 48

Step 7:
198 divided by 48 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 175954.0
The remainder is 6 after subtracting 192 from 198.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 48

Going ahead to step 8:
60 divided by 48 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1759541.0
If we subtract 48 from 60, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
The number 48 fits into 120 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 1759541.2
If we subtract 96 from 120, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
The number 48 fits into 240 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 1759541.25
If we subtract 240 from 240, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1759541.25
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 12:
48 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1759541.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 1759541.25, with a leftover of 0.0.
